  • Polymeric Esters of Aromatic Dicarboxylic Acids as Soil Release Agents
    Publication number: 20180179474
    Abstract: The cleaning power of detergents when washing textiles was to be improved. This was accomplished mainly by using polyesters that are accessible from the dicarboxylic acid terephthalic acid and possibly isophthalic acid as well as ethylene glycol and polyethylene glycol having an average molar weights ranging from 2,000 g/mol to 8,000 g/mol.

  • Catalyst compositions, methods of preparation thereof, and processes for alkoxylating alcohols using such catalysts
    Patent number: 9802879
    Abstract: A process of preparing an alkoxylation catalyst wherein a catalyst precursor which is formed from an alkoxylated alcohol, calcium hydroxide, carboxylic acid, inorganic acid, and propylene oxide, is mixed with an antioxidant, preferably butylated hydroxyl toluene. A process of alkoxylation using the catalyst of the present invention.

  • Process for the production of lower alcohols by olefin hydration
    Patent number: 8809600
    Abstract: An improved process for the hydration of C2-C5 olefins to the corresponding alcohols via heterogeneous reactive extraction with ion exchange resin catalysts is provided. The improvements are based on the application of a structured catalytic packing, a simultaneous product extraction in multiple condensed phases for enhancement of the overall alcohol production rate and a simplified product purification procedure.

  • Synthetic ester lubricants for refrigerator systems
    Patent number: 5830833
    Abstract: Lubricants for refrigeration equipment operating with fluorocarbons as refrigerants are produced by esterification of at least one neopolyol type polyhydric alcohol with an acid component comprising 60 to 80 mol percent n-pentanoic acid, from about 40 to about 10 mol percent of at least one straight chain C.sub.6 to C.sub.10 monocarboxylic acid and from about 0 to about 30 mol percent C.sub.6 to C.sub.10 branched chain monocarboxylic acid. The resulting esters are suitable for use without lubricating oil additives.

  • Homogeneous electroviscous fluids using aluminum compounds
    Patent number: 5800731
    Abstract: Homogeneous, electro-viscous fluids are provided which contain aluminum soaps based on products obtained by reacting one or more mono- or polycarboxylic acid(s) or the anhydrides or semi-esters thereof with reactive aluminum compounds, such as aluminum alcoholates. The aforesaid fluids manifest high electro-rheological effect and are completely homogeneous, and do not require a dispersant.
